The CEO of Goldman Sachs believes that bitcoin is simply just not for him.

In an interview held Tuesday, Goldman Sachs chairman and CEO Lloyd Blankfein explains that bitcoin is just not his cup of tea. When asked about the cryptocurrency, he said “it’s not for me.”

“I don’t do it. I don’t own bitcoin.”

Despite not owning the cryptocurrency, Blankfein does not feel negatively about the cryptocurrency. Though he had commented once during an interview with Bloomberg that he has a “level of discomfort” with bitcoin, Blankfein is open to it. Goldman Sachs has even been reported to be testing the waters with regards to crypto services.

The New York Times reported that the firm is developing plans for a bitcoin futures trading platform.
